252 FLORIDA GEOLOGICAL SURVEY-3TH ANNUAL REPORT

 The differences between different regions agree pretty well with those brought out elsewhere in this report about the composition and density of population, illiteracy, agriculture, etc. The western division of the flatwoods leads in several things on account of containing our largest city, for city schools of course are usually larger and more regularly attended than country schools.
 The differences between central Florida and the whole State are not very pronounced (if comparison had been made with the rest of the State instead of the whole State the contrasts would have' been magnified), but they are nearly all in the direction of larger and better schools, older, more experienced and better paid teachers, better attendance records, etc. Comparisons with other states would involve considerable labor, but central Florida is evidently well up to the United States average in most respects.* The government school statistics available do not separate the races, but in the whole country about 90% of the population (and probably a still larger proportion of the school population) is white, so that figures for white schools would not differ much from those for all schools. When the sparse population of our area is considered its excellent showing in school matters is rather remarkable.
 In Figure 43 the school populations of central Florida and the whole State, not counting the chart or kindergarten grade, is divided by races and grades. The curves are cumulative, i.e., the distance from any point on any curve to the right hand margin indicates the percentage of pupils in the group designated that have entered or passed through the grade selected. Consequently the percentage enrolled in a given grade corresponds to the horizontal distance between the points where the curve cuts the tipper and lower boundaries of the grade. The curves are all steepest in the upper grades, on account of the inevitable dropping out of pupils all along, though in some counties there are a few more in the

 *In comparing Florida with the rest of the United States it should be borne in mind that most other parts of the country are colder and therefore require more substantial schoolhouses and greater expense for heating them.
